STEP 4: Calibration calculation for south direction

The Ultra display shows: “Point to SOUTH. Press NEXT when ready”.

Have the aircraft nose pointed to the magnetic south (180°) radial on the airport compass rose.

Set the aircraft in level and straight flight attitude by using jacks or blocks.

Let the system stabilize for about 30 seconds and make sure that the aircraft is not moving.

Then confirm by pressing “NEXT”.

Note: The calibration calculation for south direction will start and a counter will inform of the

progress.

STEP 5: Calibration calculation for west direction

The Ultra display shows: “Point to WEST. Press NEXT when ready”.

Have the aircraft nose pointed to the magnetic west (270°) radial on the airport compass

rose.

Set the aircraft in level and straight flight attitude by using jacks or blocks.

Let the system stabilize for about 30 seconds and make sure that the aircraft is not moving.

Then confirm by pressing “NEXT”.

Note: The calibration calculation for west direction will start and a counter will inform of the

progress.

STEP 6: Check compass calibration

At the end of the calibration process the Ultra will confirm if the magnetometer is calibrated

successfully.

The message “Calibration done” will pop up.

Note: In the SETUP page after COM 1 will be written “ENABLED MAG”.

IMPORTANT

: Don’t power off the system. Let the system stabilize for about 15 minutes

before moving the aircraft.

Note: In the “SETUP” menu you can choose to display compass heading in reference to

magnetic north or true north (see chapter 4).

Note: If the calibration fails or the compass indicator is not enabled, repeat the calibration

procedure. If several calibration attempts fails review the installation location of the

Ultra. Magnetic disturbance could be too high in the area selected.
